The Iran war showed how fast a modern conflict burns through expensive weapons. The Pentagon’s answer — cheap drones and low-cost cruise missiles built from off-the-shelf parts — is quietly rewiring who wins in the defense trade.

The U.S. fired more than a thousand Tomahawk-class missiles in the Iran war, part of an estimated tens of billions of dollars of munitions expended. At a couple million dollars apiece, that math doesn’t scale. So the Pentagon is pivoting to cheap, attritable mass: low-cost drones and cruise missiles assembled from commercial parts. One contender — a cruise missile from Leidos (LDOS) — targets roughly $35,000 a unit, against a Tomahawk that costs dozens of times more. Startups like Anduril and a wave of new entrants are racing into the same gap.
This shift cuts two ways for investors. It pressures the old model of a few exquisite, ultra-expensive platforms — and it rewards the contractors who can manufacture cheap firepower at scale, plus the primes nimble enough to adapt. Munitions replenishment is a multi-year, high-visibility cash-flow story regardless of which way the technology breaks.
Our defense barbell stays — but this is a reason to watch the cheap-mass disruptors, not just the legacy primes. Names like Leidos (LDOS) on the low-cost-munitions side, alongside the established players (RTX and the broader complex) that supply the replenishment, capture the shift. The theme isn’t “more war”; it’s that a re-arming world is buying a different, cheaper kind of firepower.
